Electrocardiograph technicians, commonly called EKG technicians, operate noninvasive equipment which prints graphic tracings of electrical impulses transmitted by the heart. Computerized electrocardiograph equipment has the capability of analyzing the graphic tracing. The echocardiographer is responsible for maintaining the equipment and supplies, preparing the patient for the test and monitoring the patient during the procedure.

• Fields for echocardiographers include hospital cardiology departments, physicians' offices, cardiac rehabilitation centers, health maintenance organizations, or clinics.
• As the job offerings for EKG technicians decline, those that have specialized in continuous ambulatory (Holter) monitoring and cardiac stress testing will have a clear advantage over those who haven’t.
• Important skills to have, in addition to the technical aspects of the job, are interpersonal skills, attention to detail and the ability to follow instructions.
• Echocardiography also has a physical challenge to it. Especially in settings where most EKGs are performed at the patient's bedside, echocardiographers spend a significant amount of time walking and standing. Employees serving as monitor techs, on the other hand, get subjected to long hours of sitting in confined quarters.
